Description

Technical Field

[0001] The utility model relates to the field of sewage treatment auxiliary equipment, in particular to a novel jet aerator. Background Art

[0002] Aerators are equipment used for sewage oxygenation treatment. They are mainly used in the biochemical treatment of sewage. By introducing air or oxygen into the sewage, the oxygen content in the water is increased, thereby promoting the growth and activity of aerobic microorganisms and accelerating the decomposition and transformation of organic matter. Aerators can be divided into surface aerators and underwater aerators according to their usage methods. Underwater aerators mainly include microporous aerators and jet aerators. The general structure of a jet aerator includes an aeration plate (aeration shell) and an air inlet pipe. There are multiple aeration holes distributed on the surface of the aeration plate. When working, the compressed air output by the air compressor (located above the water area) is input into the aeration plate through the air inlet pipe connected to the aeration plate. The aeration holes output pressurized gas to aerate the bottom of the water (such as a sewage treatment pool, etc.).

[0003] Although the existing jet aerators meet the use needs to a certain extent, they are still limited by their structure and have some disadvantages. Specifically, the aeration disc is in a fixed working mode and can only aerate a fixed water area, and the aeration range and effect are relatively limited. In summary, it is particularly necessary to provide a jet aerator that can aerate a wider range of water areas. Utility Model Content

[0004] In order to overcome the drawbacks of existing jet aerators as described in the background due to structural limitations, the utility model provides a new type of jet aerator based on a jet aerator body, which, under the joint action of relevant mechanisms, can be used to aerate positions of different depths and circumferential directions of corresponding waters in a rotating manner, thereby achieving relatively better aeration effect in more areas.

[0007] Furthermore, the jet aerator body, the cylinder and push column of the electric push rod, the linear bearing, the driving gear, the driven gear and the connecting pipe are made of stainless steel.

[0008] Furthermore, the driving gear and the driven gear are meshed, and the number of teeth of the driving gear is less than the number of teeth of the driven gear.

[0009] Furthermore, the control circuit includes time-controlled switches connected via circuit board wiring, and power input ends of the two sets of time-controlled switches are electrically connected respectively.

[0010] Furthermore, water seal rings are respectively installed between the inner and outer rings at the upper and lower ends of the bearing.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the utility model is based on the jet aerator body and has all other functions of the common jet aerator. Under the joint action of the control circuit, the electric push rod and the linear bearing, the utility model can push the aeration tube up or down cyclically at regular intervals, and the motor reduction mechanism can drive the aeration tube to move in the circumferential direction through the driving gear and the driven gear. In this way, the utility model can aerate the corresponding water area at different depths and different circumferential directions in a rotating manner, and play a relatively better aeration role.

The left side of the connecting pipe 103 and the right outer end of the aeration shell 101 are welded together and communicate with the inside of the aeration shell 101. The right side of the connecting pipe 103 and the exhaust pipe of the air storage tank of the air compressor above the water area are connected through a pipeline. There are three sets of linear bearings 4. The upper ends of the shafts of the three sets of linear bearings 41 are distributed in annular shapes and vertically spaced apart and are respectively welded around the lower end of the aeration shell 101. The lower ends of the bearing seats of the three sets of linear bearings 4 are distributed in annular shapes and spaced apart and are respectively welded around the upper end of the fixed plate 5. The lower end of the cylinder of the electric push rod M2 is bolted to the middle of the upper end of the fixed plate 5. The upper end of the column is welded to the middle part of the lower end of the aeration shell 101; the middle part of the upper end and the right end of the aeration shell 101 are respectively provided with an opening, and a bearing 104 is respectively welded in the two openings. The lower end of the waterproof motor reduction mechanism M1 is bolted to the middle part of the lower right end of the aeration shell 101, and its shaft is tightly sealed inside the inner ring of one of the bearings 104, and the upper end of the shaft is located outside the upper end of one of the bearings 104, and the driving gear 2 is welded to the outer side of the upper end of the shaft; a connecting pipe 105 is welded in the inner ring of the other bearing 104, the upper end of the connecting pipe 105 is welded to the middle part of the lower end of the aeration pipe 102 and communicates with the inside of the aeration pipe 102, and the upper and lower ends of the aeration pipe 102 have a plurality of aeration holes 106 at each interval, and the middle part of the driven gear 2 is welded to the outer lower end of the connecting pipe 105; the power module W1, the power switch S1, and the control circuit 6 are installed in the electric control box above the water area.

[0016] Figure 1 , 2As shown in the figure, the jet aerator body, the cylinder and push column of the electric push rod M2, the linear bearing 4, the driving gear 2, the driven gear 3, the connecting pipe 105, etc. are all made of stainless steel. The driving gear 2 and the driven gear 3 are meshed, and the number of teeth of the driving gear 2 is less than the number of teeth of the driven gear 3. The control circuit includes time-controlled switches W2 and W3 connected by circuit board wiring, and the power input terminals 1 and 2 of the two sets of time-controlled switches W2 and W3 are connected by wires. Water seal rings 107 are installed between the inner and outer rings of the upper and lower ends of the bearing 104. The motor reduction mechanism M1 is connected in series via the power switch S1 (the handle is located outside the front opening of the component box), the power input terminal 1 and 2 pins of the power module W1 and the two poles of the AC 220V power supply are connected via wires, the power output terminal 3 and 4 pins of the power module W1 and the power input terminal 1 and 2 pins of the control circuit time control switch W2, W3 are connected via wires, the power output terminals W2, W3 (3 and 4 pins) of the control circuit and the positive and negative or negative and positive power input terminals of the electric push rod M2 are connected via wires.

[0017] Figure 1 , 2 As shown, the new type is based on the jet aerator body and has all other functions of ordinary jet aerators. When working, the compressed air output by the air compressor (located above the water area) is input into the aeration shell 101 through the connecting pipe 103 connected to the aeration shell 101, and the aeration hole 106 of the aeration pipe 102 outputs pressurized gas to aerate the bottom of the water (such as a sewage treatment pool, etc.). After the AC 220V power supply enters the power input end of the power module W1, the 3rd and 4th pins of the power module W1 output a stable DC 12V power supply to enter the power input end of the control circuit. After turning on the power switch S1, the motor reduction mechanism M1 is powered on and its shaft drives the driving gear 2 to rotate, and the driving gear 2 drives the driven gear 3 to reduce the speed and increase the torque to rotate (about 6 revolutions per minute). In this way, the connecting pipe 105 drives the aeration pipe 102 to rotate in a 360-degree mode, and the aeration pipe 102 will aerate the relevant waters in a 360-degree direction. After the time switches W2 and W3 are powered on, their 3rd and 4th feet will cyclically output positive and negative or negative and positive bipolar power to enter the power input end of the electric push rod M2 (for example, the 3rd and 4th feet of the time switch W2 first output power for 8 seconds, and then the 3rd and 4th feet of the time switch W3 output medium power for 8 seconds). During the time when the positive and negative bipolar power input ends of the electric push rod M2 are powered, its push column will push the aeration tube 102 to move upward, and during the time when the negative and positive bipolar power input ends of the electric push rod M2 are powered, its push column will push the aeration tube 102 to move downward. Through the above, the new type can cyclically push the aeration tube up or down at regular intervals, and the motor reduction mechanism can drive the aeration tube to move in a circular direction through the driving gear and the driven gear. The new type can aerate the corresponding water area at different depths and different circumferential directions in a rotating manner, thereby achieving a relatively better aeration effect on a wider range of water areas. Figure 2In the invention, the power module W1 is a finished product of a switching power module of 220V AC to 12V DC; the motor reduction mechanism M1 is a coaxial motor gear reducer with a working voltage of 220V AC and a power of 100W; the electric push rod M2 is a finished product of a reciprocating electric telescopic rod with a power of 100W; the time control switches W2 and W3 are finished products of a time controller module of model KG316 (mature technology, and the working principle thereof will not be described in detail in this application), which has two power input terminals, two power output terminals, and seven setting buttons. The user can set the time interval for the two power output terminals to output power by operating the seven setting buttons respectively.
